Title: Improvements in or relating to filters
IPC: B01D39/20
Filed: 1922-07-17
Abstract: 202,143. Bechold, H. July 17, 1922. Sterilizing liquids.-In order to secure a sterile filtrate, materials such as diatomaceous earth, cellulose, clay, sand, gravel, and coke, used for filtering water, fruit juices, serum, toxins, and other liquids, are impregnated with metals having a lower solution tension than hydrogen or compounds of such metals which are not readily soluble. In the case of metals, two are used together and the metals are of higher solution tension than platinum, or one is of higher solution tension than platinum and the other of lower solution tension than silver. Suitable substances include copper, copper oxide, copper ferrocyanide, copper carbonate, silver, silver oxide, silver sulpho-cyanate, silver chloride, silver chromate, mercury, mercuric oxide, mercurous chloride, bismuth, bismuth trioxide and pentoxide, arsenic, antimony, and antimony oxide. Amalgams or alloys may be used. The impregnating-materials mav be deposited in the filtering-mass by chemical action therein, or introduced in a gaseous state. Auxiliary substances which will serve to maintain a uniform distribution of the active material may be used. In one example, filtering-material is impregnated with silver chloride by first introducing gaseous ammonium chloride and then a solution of silver nitrate. In a second example, the filtering-material is treated successively with solutions of tannin or albumen, mercuric chloride, and caustic soda, the material being thus impregnated with mercury or mercuric oxide. In a third example, filtering-material is impregnated with copper by treating it with a solution of copper sulphate mixed with cane sugar or dextrin and then drying and heating.

Abstract: 1,146,847. Automatic attitude control. FEDERAL REPUBLIC OF GERMANY, DEFENCE, MINISTER OF. May 4, 1966 [May 11, 1965], No.19723/66. Heading G3R. The attitude of equipment mounted on a vehicle or craft is stabilized about an axis by a servomotor. automatically controlled in dependence on the total torque exerted on the equipment. In Fig. 2, a radar aerial reflector 2 is mounted for rotation about a horizontal axis 3 on a member 4 which is rotatable about a vertical axis on a craft 1. Signals U 6 , U 7  dependent on forces between the craft and member 4 are mutally opposed to produce a signal U 3  representative of the torque exerted on reflector 2 about axis 3 by movements of the craft Signal U 3  is applied through an amplifier 8 to control a revisible AC, DC, or hydraulic servomotor 7b which applies torque to reflector 2 in a direction opposite to that produced by movements of the craft so that the reflector is maintained substantially stationary in space. A signal U 4  dependent on motor torque, measured as a current or a pressure difference, is opposed to signal U 3  to maintain equality between the two opposed torques applied to reflector 2. To select a new attitude, a switch 14 is changed over so that servomotor 7b may be repositioned by a controller 9. Modifications are described in which (a) the servomotor is mounted on the reflector and rotates a mass about axis 3 so that the reaction applies torque to the reflector (b) the torque exerted by the craft on the reflector is detected by accelerometers (c) a similar system is provided for stabilizing the reflector about a vertical axis.

Abstract: 1473915 Making pipes; seaming MANUFACTURERS SYSTEMS Inc 8 May 1974 [26 Oct 1973] 20351/74 Headings B3A and B3J [Also in Divisions F2 and B4-B5] A machine (Fig. 18) for forming a corrugated flexible tube 20 form a strip of metal 23 comprises several drivable rollers 24-31 for forming a number of longitudinally extending corrugations and oppositely extending free edge portions (Fig. 8) in the strip, a guide die 34 arranged to receive the strip from the rollers to preform the free edge portions for subsequent interlocking, and means for receiving the strip from the guide die and curving it into a helix in which one free edge portion engages the other free edge portion so as to form a seam. Such means may comprise a pair of powered rollers 37, 38 to receive the strip from the die 34, the strip then engaging a curvature-inducing roller 39 and guide rollers 41, 42 which are set at an angle so as to direct the strip in a curved spiral path such that adjacent free edge portions of the strip overlap before again reaching the powered rollers 37, 38. These rollers have free end portions (Fig. 11) whereby the interlocked seam is constructed prior to finishing (Figs. 12, 13; not shown) by passage through a pair of powered finishing rollers (45, 46). The guide die 34 is a tunnel structure with vertically extending side walls at the entrance aperture, parts of these walls curving inwardly towards the exit to provide the required shaping. A cut-off table 53 (Fig. 18) supports the formed duct 20 over a saw assembly 54. The position of a microswitch 56 relative to the saw assembly controls the length of duct to be cut since, when the end of the duct 20 engages the microswitch 56, motors 57 and 58 are started, these driving the saw and a level wind screw 64 respectively. A solenoid 59 is also activated, this causing the saw assembly 54 to rise about a pivot 60. The level wind screw drives the saw assembly forward at a rate adjusted to equal that at which the duct is formed. Thus the tube is cut while it is rotating and moving forward. After cutting, the saw assembly 54 engages a microswitch 65 which deactivates the motor 57 and the solenoid 59. The saw assembly is then returned to its original position by the level wind screw 64, a microswitch 66 shutting off the motor 58, ready for repetition of the cycle.
